@NITED an opinion.

WILLIAM G. MILLER, OF KANSAS CITY, MISSOURI.

PRESSURE-REGULATOR.

Application filed October 30, 1916.

To all whom it may concern:

Be it known that I, WILLIAM G. MILLER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Pressure-Regulators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to pressure regulators and more particularly to a device of this character for use in a gas line to reduce the pressure of and stabilize the fiow of gas to apparatus requiring a relatively low pressure and constant supply, the present device being an improvement on that disclosed in my copending application filed May 27 1915, and serially numbered 30,7:69, the object of the present invention being to provide improvements in the details of structure disclosed in the first application.

In accomplishing these objects I have provided the structure disclosed in the accompanying drawings, wherein Figure I is a perspective view of a pressure regulator containing my improvement.

Fig. II. is a transverse section on the line II-II, Fig. IV.

Fig. III is a verticalsection on the line IIIIII, Fig. IV.

Fig. IV is a central longitudinal section on the line IV-IV, Fig. III.

Referring more in detail to the drawings:

1 designates a housing, which is preferably formed from a single casting, having an interior partition 2, dividing the housing into separate float and valve chambers 3i respectively, and having an opening 5 at its lower edge through which fluid may flow from one chamber to the other and within" which a float controlled valve beam 6 may operate.

The housing 1 is open at the bottom, but when the device is assembled is closed by a plate 8 that may be attached to the body of the housing by bolts 9, the joint between the housing body and its plate being protected against leakage by a suitable packing (not shown).

Specification of Letters Patent.

Patented Apr. 11?, 191%.

Serial No. 128,436.

Extending through the top of the housing into the valve chamber 4, are supply and outlet conduits 11-12, and attached to the housing is a head 13, having a supply channel 1% leading to the housing channel 11, and an outlet channel 15 leading to the outlet channcl 12 in the housing body; said supply channel 1 1- having a contracted neck 16 forming a valve seat 17 therein.-

The supply channel 1% opens through the side of the head 13, and communicating with the said channel is a supply pipe 19, the outlet channel also opening through the side of the head and having communication with an outlet pipe 20 that may lead to the apparatus to be supplied from the regulator, the pipes 19 and 20 being rigidly attached to the head 13 by a flange or the like 21 in any suitable manner.

The outlet channel 15 is controlled by a valve .23, which is preferably of the needle type as shown, and comprises the stem 24: and hand wheel 25, although I do not. wish to be limited to this particular form of valve.

Pivotally mounted between depending ears 26 on the top of the housing 1 is a beam 27, that is turned downwardly in the valve chamber and extends through the opening 5 in the partition 2, so that-its free end is located within the float chamber, where it carries a float rod 28 that is pivotally mounted on the end of the beam and is threaded at its upper free end to adjustably mount a float 29. The float 29 is preferably of the inverted cup type with the rod 28 threaded into a boss 30 at its upper end, which normally projects through an aperture 31 in the top of the housing into a pocket 32 in a cap 33 that is bolted to the top of the housing and covers the aperture 31, the cap havinga tight joint with the housing in order to avoid leakage.

Pivotally mounted on the beam 27 within the valve chamber is a stem 35 that projects through the channel 11 in the housing 1 into the channel 14 in the head 13, the stem having a needle point 36 adapted for cooperation with the contracted neck 16 of the channel to close or regulate the channel according to the position of the beam; the beam and float being counter balanced by a weight 37 mounted on the end of the beam within the float chamber.

In order that the contents of the separate chambers may be Observed from the exterior of the housing I provide the housing with the recess 38 in its side which communicates with the interior of the housing through openings 39 and cover the recess with glass or the like, so that the operation and contents of the housing may be observed.

In assembling the device, the beam 27, with the valve stem 35, float rod 28 and float 29 in place, islocated within the housing and pivotally mounted between the ears 26, with thelower portion of the beam located Within the channel 5 of the housing partition, the stem 35 projected into the housing channel 11 and the neck of the float projected through the channel 31 in the top of the float chamber. The bottom plate 8 is then applied to the lower end of the housing and the housing filled with liquid to the desired depth.

The cap 33 and head 13 are then attached to the top of the housing, with the channels and pocket 32 registering with the cooperating openings of the housing, and the intake and supply conduits are properly attached to the head 13 and connected with a suitable source of supply and with a gas using apparatus.

Gas under high pressure is then admitted to the intake channel let, and accumulating in the space in the valve chamber above the liquid, is fed through the outlet channel to the using apparatus. As the incoming gas is at a higher pressure than is desirable for use in the apparatus it will force the liquid in the valve chamber downwardly through the channel 5 into the float chamber and when suflicient pressure is present in the valve chamber will effect the lifting of the float, so that the beam 6 is lifted to actuate the valve stem 35 to close the inlet 14, it being apparent that as the pressure in the valve chamber increases with the increase in supply, the float is proportionately lifted and the supply shut ofl". By proper regulation of the float 29 on its supporting stem, an equilibrium may be established that controls the flow to the housing, so that a constant supply under a determined pressure may be provided to the using apparatus, any increase in the pressure of supply effecting the displacement of liquid in the valve chamber to lift the float and shut off the supply until the equilibrium is reestablished. 7

It is apparent that the needle valve or its equivalent will admit a limited flow through the valve seat and that the flow is determined directly by the position of the valve seal between the separate chambers that prevents escape of the gas from one chamber to the other. 7

Having thus described my invention what I claim as new therein and desire to secure by Letters-Patent, is

1. A pressure regulator comprising a housing containing separate valve and float chambers having a communicating channel, the valve chamber having intake and outlet channels, a beam pivotally mounted in one of said chambers and extended into the other, a valve connected with the beam and located in the valve chamber, and a float connected with the beam and located in the float chamber.
